To display a dialog with wxPython requires only a few lines of code. We will demonstrate that below:

Information dialog An information dialog can be shown with one line of code:

import wx
app = wx.App()
wx.MessageBox('Pythonspot wxWidgets demo', 'Info', wx.OK | wx.ICON_INFORMATION)

The first parameter is the actual text to display. The second is the title and final parameter tells wx to show the information icon and button.

Output:

wx dialog

More dialogs: Warning dialog, Error dialog and default dialog By modifying the parameters you can easily create other types of dailogs. An example below:

import wx
app = wx.App()
# simple dialog
wx.MessageBox('A dialog', 'Title', wx.OK)
# warning dialog
wx.MessageBox('Operation could not be completed', 'Warning', wx.OK | wx.ICON_WARNING)
# error dialog
wx.MessageBox('Operation could not be completed', 'Error', wx.OK | wx.ICON_ERROR)

Output (only one of the dialogs):

wxDialog

Question dialog Wx can be used to create a question dialog (yes/no). Example code:

import wx
app = wx.App()
dlg = wx.MessageDialog(None, "Do you want to update?",'Updater',wx.YES_NO | wx.ICON_QUESTION)
result = dlg.ShowModal()
if result == wx.ID_YES:
    print "Yes pressed"
else:
    print "No pressed"

Output:

wxDialog
